You did not say where you are located. I had mine built with what I believe you mean by a dog house by C and D cases. I had a removable trap door put in the back so the case can be closed and all the wires can still be connected. I could then chain the closed case to a table. Nice job. I had them build triangle wedges out of foam to raise the angle of the mixer (10 to 15 degrees, I forget) but not raise the wrist pad height. I can see the video display better. The wedges come out and store right in the case. I was also able to store the LED lamp right in one of the wedges so it was a wedge and a lamp carrier in one.
